The ancients divided the great summer heat into three periods, namely: "A rotten grass is a firefly; Second, wait for the soil to moisten the summer heat; When it rains, it will be fine. " Summarize the corresponding phenological phenomena in each period, that is, the "response" of the three periods of great summer heat, including animal response, plant response and natural phenomenon response.

1, a rotten grass is firefly.

During the summer heat, fireflies hatched. The ancients believed that fireflies were changed by rotten grass. Fireflies, also known as "Candle Nights" and "Yao Nights", were poetic insects that greeted beginning of autumn in the summer. When fireflies shuttled in the quiet night, the cool autumn was not far away.

2. Wait for the soil to moisten the summer heat.

The weather began to be sultry and the land was wet. It's wet, and in the heat, the humidity is heavy, and the heat and humidity are unbearable. Liu Xi of the Eastern Han Dynasty said: "Summer is boiling, the internal heat is down, the sun is up, and fumigation is damp and hot. If people are in a steamer, their gas is extremely dirty, which is also called' dirty heat'." .

3, three wait for heavy rain.

During the hot summer, due to the accumulation of moisture, it often rains heavily, and there are often heavy thunderstorms, and the weather begins to transition to beginning of autumn.
